I am writing to you since I am trying to build a small cluster with odroid-C2 equipped with a eMMc 16GB Module C2 Linux. I tried to install openmpi (different versions), mpich (different versions) from source and also using apt-get in any case, once the installation is concluded without any error message (and the installation seems to be done) I try to run mpirun, mpicxx, etc ... and I got always the same error message... Illegal Instruction. I tried to check on the web but I didn't find any information about this error.

Can you kindly help me with such issue?

Thank you very much in advance for your collaboration.

Kind regards,

Would you be able to share the error logs with a command you invoked? Also you can run both commands and show us what it says.file mpirununame -a
